What filters do
Hood baffle filters knock grease droplets out of rising kitchen air. They protect the rest of the system — but only if they're cleaned often.
What full cleaning does
Even with perfectly maintained filters, grease accumulates in the hood plenum, the duct interior, and the exhaust fan. None of that is reachable through the filter slots.
The right routine
Weekly filter washing by kitchen staff, plus a full professional cleaning at the NFPA-96 frequency for your cuisine type. The two together keep the system safe.
